like a child in a sweet shopBRITISH
If you are like a child in a sweet shop in a particular situation, you are very happy and excited because of something you can do or have, and often behave in a greedy or uncontrolled way. With so many options before me, I was like a child in a sweet shop. Note: The usual American expression is like a kid in a candy store.
